Issue with select2 (modal not working, editing not working)

[ludekvodicka]

It seems there is an issue in select2 initialization

Based on this post: https://stackoverflow.com/a/46549199/113842

it's necessary to add following line to createDialog select2 initialization:

columnDefs[j].select2.dropdownParent = $("#altEditor-modal-" + this.random_id);

a whole code should look like this:

  // enable select 2 items, datepicker, datetimepickerm
          for (var j in columnDefs)
          {
            if (columnDefs[j].select2)
            {
              columnDefs[j].select2.dropdownParent = $("#altEditor-modal-" + this.random_id);
              $(selector).find("select#" + columnDefs[j].name).select2(columnDefs[j].select2);
            }

after that, select2 will work as expected
